pstore/ram: Rate-limit "uncorrectable error in header" message
There is a quite huge "uncorrectable error in header" flood in KMSG on a clean system boot since there is no pstore buffer saved in RAM. Let's silence the redundant noisy messages by rate-limiting the printk message. Now there are maximum 10 messages printed repeatedly instead of 35+.
